ll/lOlSTENlNGATTACHMENT FOR 8l-EOE SEVViNG MACHINES.

SPECIFICATION forming part of Letters Patent No. 378,759, dated February 28, 1888.

Application filed May 9, 1587.

T (tZZ whom it may concern:

Be it known that I, GnoRc-n BLAKENEY, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Moistening Attachment for ShoeSewing Machines, of which the following is a specification.

My invention consists in an attachment or appendage to machines for stitching or sewing together the sole and upper of a shoe or boot, whereby water or other lubricant is automatically conducted to that part of the trough of the sole-groove which is about to be pierced by the stitching-needle.

In the accompanying drawings, Figure I is a front elevation of my said appendage and of contiguous parts of a shoe-sewing machine,all in their normal or inactive condition. Fig. II is a side elevation of certain of said parts. Fig. III is a section on the line III III, Fig. II. Fig. 1V is a transverse section of a shoe, with part of the nozzle of the water-carrier. Figs. V and VI are transverse sections of the waterdelivering cool; in its closed and open conditions, respectively. Fig. VII is a vertical sec tion (parallel with the feed) of the discharging portion of the waterduct.

1 and 2 respectively represent parts of the frame and of the horn for stitching ashoe-sole to its upper.

3 represents the presser foot, and 4t its holder.

5 shows a vertically-rcciprocated fulcrumpost that differs from the customary vertically-reciprocated fulcrumpost in possessing a downward extension or prolongation below the lower guide of the frame and in having said prolongation armed with a lateral projection or pin, (3, for a purpose to be presently explained.

A bracket, 7, (which may be vertically adjustable, as shown,) supports a water tank or reservoir, 8, from which a pipe or a flexible hose, 9, leads to cook or valve 10, whose spigot 11 has slotted arm 12, which receives and is periodically vibrated by the pin 6, that projects from the reciprocating fulcrum-post 5. The ventage 13 of the cock communicates, when the cock is open, with a second pipe or hose, 9, which conducts into a passage, 14, in the presser-foot holder at, which passage emp- Sorinl No. 237,590. (No model.)

I ties into the discharge-nozzle 15. The loca tion of the said discharge-nozzle 15 is such as to place its ventage in such close proximity to the side of the said pres'ser-foot remote from the needle as to convert the said foot side or surface into a surface conduit (operating by capillary attraction) for the escaping water into the trough or bottom of the sole-groove.

The disposal and proportions of the operative parts are such as at each descent of the needle to cause a small predetermined quantum of water to drip or trickle along the exterior surface of the presser-foot into that portion of the trough of the solegroove which is about to be penetrated by the stitchingneedle. The stock being lubricated and rendered pliant and elastic by the application to it of the water in the manner and place stated, yields without tearing to the stitching-needle, and 011 the retreat of the latter closes compactly around the chain or stitch, which, not encountering any of the asperities character istic of dry sole-leather, can be drawn tightly and with economy of thread and with intimate contact of sole and upper into the thus temporarily-softened stock. The wetting being restricted to the trough of the groove and the contiguous underlying parts of the insole, the shoe is not rendered unsalable by staining or buckling of the exposed surfaces which accompanies the manual application of water as now sometimes practiced.

The described location of the nozzle, while securing thorough moistening of the objective parts, makes it impossible that any water should reach the horn orifice and its contained mechanism.

The abovedescribed preferred form oli my invention may be varied as to some of its details. For example, the water-supply may be regulated wholly or partially by an ordinary faucet, 16, or other suitable device or expedient under direct control of the operator.

The automatic opening and closing of the regnlating'cock may be obtained by connection with any suitable moving member, and may be itself adjustable, if desired.

Substantially uniform water-pressure may be derived from any customary or suitable mechanical expedient, such as a water-trap,

2 7 isfis a steam generator, or an ordinary hydrant service-pipe.

I claim herein as new and of my invention-- 1.. The combination, with the horn, presser- 5 foot, and needle of a shoesewing machine, of

a water-head whose ductleading therefrom has a discharge-nozzle near the resser-foot on the side remote from the needle,and a cook or regulator whereby the stock is moistened immero diately in advance of the descending needle,

substantially as and for the purpose set forth.

2. In combination with the horn, presserfoot,needle,andreciprocatingfulcrum-postof a shoe-sewing machine, a Water-head whose duct leading therefrom has a discharge-orifice near 15 the presser-foot on the side remote from the needle, a cock, and connections between the fulcrum-post and the cock whereby the cock is periodically operated by the said post, sub stantially as and for the purpose set forth.

In testimony of which invention I hereunto set my hand.

GEORGE BLAKENEY.
